I ended up lubricating the heat sink fan on an NVIDIA GeForce GTS240 whilst looking for the cause of a PC error from it.
During the last couple of months I had some serious errors (about 4) reported on my HP Z620 PC.
These were two of the error reports:
- 928 – Fatal PCIe error. PCIe error detected Slot 2 Completion timeout.
- 928 – Fatal PCIe error. PCIe error detected Slot 2 Surprise link down error.
All the errors pointed to either a Slot 2 problem or a problem with my NVIDIA GeForce GTS240 Display Adapter in that slot. I hoped the problem (which is intermittent and very occasional) would go away if I reseated the Display Adapter in its PCIe card slot.
This article describes what I did next and how I ended up lubricating the heat sink fan.

This article describes the Dyson Slim DC18 Filter Cleaning process for the Pre-filter and the HEPA (Highly Efficient Particle Arrester) Post-filter.
Many devices in this world which pump air have air filters installed to prevent dirt getting into mechanical parts and clogging them up to the point where they perform badly or fail. The air filters clog instead and have to be replaced or cleaned at regular intervals. The Dyson Slim DC18 is no different. It has two air filters:
A Pre-filter (before the motor) which requires periodic cleaning by the user every 3 to 6 months under normal usage. This sits on top of the Cyclone within the Cyclone Assembly and is placed between the Cyclone and the motor. It prevents dirt entering the motor bearings or clogging up the space around the rotor.
Post-filter (after the motor) which doesn’t require user attention. This sits on top of the motor and filters the air leaving the DC18. It captures allergenic particles which have been drawn into the cleaner and prevents them being reintroduced to the local atmosphere.
The method of cleaning the Pre-filter, on all the Dyson machines that I have seen, requires the air filter to be washed with water under a running tap. This is an easy way to clean a filter which is designed to be flexible so that it can be squeezed to remove the water it absorbs in the washing process. The dirt is washed away and doesn’t get into the air which would cause a breathing hazard for the user. Continue reading “Dyson Slim DC18 Filter Cleaning”
